Abstract
Automated processes that dynamically control rate of delivery of molten metal to a mold during a casting process. Such automated processes can use dynamic metal level variation, control pin pulses and/or oscillation during the mold fill and transient portion of the cast. It has been found that such pulses keep metal flowing in a manner that addresses problems, particularly at the beginning of an ingot cast, associated with metal meniscus contracting and pulling away from the mold on the short faces and corners.
